DROP cluster

Drop is:

drop.astron.nl

With 6 nodes at 8 cores each, DROP is designed for non-interactive queue-based parallel supercomputing.

Drop is not:

For anything that is interactive, uses less than 8 parallel cores per job, is not queue-able, or generally takes less than a few nights to run on your desktop, you had better use one of the stand-alone servers.

Drop has only scratch storage. Move important data to a different server. Anything on /data/ can be deleted without notice.

Kindly note that this cluster comes 'as is' with no support from IT, Joeri or Jason.

The main node is the file server. Do not run jobs there, in for- or background.

Come see Joeri for an account

File systems

/export/home/<user>

RAID6, 20GB/user quota, nothing ever auto-deleted

/data (crossmounted over all nodes) = RAID0, unlimited space

RAID0, 5TB, no quotas

heaviest users will have older data auto-deleted by semi-random script, so better clear it out yourself
